Data Protection and Email in Turkey

Email compliance in Turkey intersects with broader data protection requirements.

**Primary Data Protection Law:** KVKK (Law 6698)

Email addresses are personal data under most national data protection frameworks. Collecting, storing, and using email addresses requires a valid legal basis — in most opt-in countries, this is explicit consent. Organizations must also comply with data subject rights including access, rectification, and erasure requests.
